Office Lab 2
============

Description
-----------
This dataset contains sensor data that was collected in the office of a 2 PhD researchers at KU Leuven, Leuven, Belgium over a period of approximately 6 
months. The files contain raw sensor events, no activities are annotated.

The sensor events are generated from multi-sensors, comprising a motion sensor (these files begin with "Motion" followed by the sensor number), a 
temperature sensor (these files begin with "Temperature" follewed by the sensor number), a relative humidity sensor (these files begin with "Humidity" 
followed by the sensor number) and a photo resistor measuring light intensity (these files begin with "Light" followed by the sensor number). In addition, 
a door closure sensor is attached to the door (this information can be found in the file named "Door"). Furthermore, reed-contacts are attached to the 
occupants' seats, registering when they are seated (these files begin with "Chair" followed by the sensor number). Finally, a current clamp is used to 
measure the energy consumption of an auxiliary electrical heater (this information can be found in the file named "Heater Energy").

Notes:
-----
- The motion sensors are dedicated to one user by orienting them such that they cover the part of the office occupied by the respective user.
- The reed-contacts on the chairs occasionally got stuck in either position, resulting in an incorrect state for some periods of time.
